Only watched this because I really liked Checkmate and this had the same theme and cast. However, I didn't expect a debacle of these proportions. How this has an 8.4 rating here is beyond me, unless its because of actor fans; but then different strokes for different folks.

Pros: Literally the SML or QCS carried the entire show on his shoulders. His character was intelligent, gutsy, had great martial arts skills, loyal, caring, supportive to all he cared about. Maybe not the full brains of the operation, but very close. Other likable characters were Old man Bai, Adou, and Salim. They rounded out the support nicely. Production when it came to sets and costumes was gorgeous as all Republican era dramas are. That's it, there were no other pros for me.

Cons: I could just say everything else and that would suffice but I will elaborate a bit. The ML had serious issues of laziness, greed, and multiple personalities that only seemed to slightly disappear towards the end. The FL was the usual toxic, prepubescent voiced, self entitled brat that thought the entire world owed her for her father's lack of parenting skills. There was zilch chemistry between the leads other then constant bickering, so them getting all lovey dovey towards the end and getting hitched was very much an afterthought that felt more like incest because they acted like siblings with QCS having to essentially babysit both even during cases, which made things look very unprofessional and half-assed.

The plots and cases were rather dull and unsatisfactory; all suspects confessed very quickly after always repeating the same remark about evidence; there was no real pull between ML and murderer. Like "Yep ok, I confess". The European additions to the cast had to be the worst and what got hit for ratings first for me was the nasty anti-Semitic remarks by both the Chinese and European cast. While I understand the time period and things were up in the air in China politically, Jews never posed a threat and therefore the Fascist comments were not only unnecessary but revolting. Had that continued, I would have dropped the series on principle.

The lack of cohesion of the Europeans speaking English, with their lips moving inaccurately to what was being said was sometimes hard to watch and often caused a headache. Also what was the point of them speaking English to their Chinese counterparts only to switch to Mandarin? It looked very sloppy. The ending was rushed and felt like it was filmed in a day. This was basically a train wreck in a fancy wrapper.

Would I recommend it? No, I absolutely would not. Yes, this was somehow a spoof on something to do with Agatha Christie, but for the life of me, I don't know how or where. This is probably one of my shortest reviews for a show, because it had literally just about everything wrong with it. So, save yourself the headache and find something else.
